- ing of the rubber roxn the center toward the outside of the tire,which is a common fault with many of the tires heretofore in use.

I have shown two embodiments of my inr vention, but changes may be 'madetherein without departing from the same as defined in the appendedclaims, it being specially pointed .out that the arrangement of thetrend lugs on-the tire itself maylbe varied in many difierent ways, andso the general configuration o f the tread lugs may also bevaried,withoutdeparting from the spirit of the invention, as defined by theappended o] aims.

I claun:

1. An improved tread liig for tires, hav-' ing its rear-portion ofsmaller height than its forward entering prtion and constantlyincreasing in width from its forward entering portion to itsrea'r-portion.

2. An improved tread lug for tires, having a forward-portion of greaterheight than the rearWard-portion and constantly decreasing in heightfrom the forward-portion to the ree-rWard-portion, and having its forWard or entering portion of smallest width and having the width of thetread 111g constantly increasing from the forward-portion to therearWard-portion.

3. An improved tire having a plurality of trend lugs thereon, eachhaving the forwardportion of greater height than the rear-por- 'tion andits forward'portion of smaller width (th an its rearward-portion, andhaving one line of tread lug.q arranged longtudinelly on the tire inline with the longitudinal line of thev tire, and having a row of treadlugs at either side thereof, each of said trend lugs being arranged'atthe same angle to the central row of tread lugs. v

In testimony, that I claim the foregoing as my invention, I have signedmy name in presence of two subscribing witnesses.
